cm) diagonal 800 x 600 (SVGA) resolution rear-projection display system designed around Texas Instruments’ proprietary Digital Light Processing™ (DLP)™ technology. The display features low power consumption, long lamp life and excellent focus and geometry with a sharp true-to-life color spectrum. The display utilizes the same modular form factor as the company's other award winning, VideoWall display products, while providing the benefits of DLP technology. The WN-5230-S offers consistent color and brightness uniformity across the high-contrast screen, and doesn’t have the color drift, image retention, or convergence problems associated with CRT based rear-projection systems. The WN-5230-S provides the same high image quality, reliability, light weight and brightness levels typical of Clarity display products. Features • • • • • • • • • • optical resolution of 800x600 pixels low 160 watt power consumption long 8,000 hour average lamp life superior image quality (even in high ambient light conditions) light weight – 120 pounds (55 kg) thin – 30.6 inches (77.7 cm) improved brightness uniformity (no “hot spots”) consistent colors displayed on adjacent modules no color drifting no convergence problems 1 Options and Accessories Clarity’s display products can be upgraded with several accessories. See your reseller or visit www.ClarityVisual.com for a current listing of available options. ! Ultra-Thin Mullion Screen – There are three screen options: • The standard screen has a mullion 1/8 (3 mm) wide. The mullion is a strip of sheet metal surrounding the screen which holds it in place. • The Ultra-Thin Mullion Screen, or mullionless screen, does not have the 1/8” (3 mm) strip of sheet metal around the screen. The edge of the screen goes right to the edge of the display unit, which makes the lines between display units almost invisible in the finished video wall. • BlackScreen™, a mullionless screen as above, but with a higher contrast ratio. ” ! S/300 - Video Input Module This adds three new inputs – composite and S-video in NTSC, PAL, and SECAM – and a 15.75 kHz line-doubling capability for RGBS. ! Clarity’s Big Picture™ Big Picture spreads a single video source over an entire video wall, eliminating the need for an external processor. (All display units in the video wall must have this option.) The S/300 option, above, is included with Big Picture. ! SRT-100 Screen Removal Tool This tool makes it easy to remove the normal mullion screens when the displays are used in video walls, where units are placed directly adjacent to each other. The SRT100 minimizes the chance of damaging the screen and the screen’s latches. (Used with standard mullion screens only.) ! SAT-500 Screen Alignment Tool This tool is essential to properly position the display units with the Ultra-Thin Mullion Screen in a video wall. It assures the correct spacing between adjacent screens in the assembled video wall. (Used with Ultra-Thin Mullion screens only.) ! BAS-520 Base for the WN-5230-S The BAS-520 provides a permanent attachment to flooring. 2 September 1999 WN-5230-S VideoWall User’s Guide Safety Please read this chapter carefully before attempting to install, use, service, or repair the WN-5230-S VideoWall.

Do not attempt to replace the projection lamp module with any alternative light source. Doing so can cause overheating or unacceptable image quality. Replacement lamp modules may be ordered from Clarity Visual Systems, Inc. Use only the projection lamp module specified by Clarity Visual Systems, Inc. or an authorized Clarity Visual Systems, Inc. Service center. Use of any other lamp voids the warranty. WARNUNG Der WN-5230-S benutzt ein Projektionslampenmodul von hoher Intensität. Versuchen Sie nicht, das Projektionslampenmodul mit irgendeiner alternativen Lichtquelle zu ersetzen. Dies könnte zu Überhitzung oder nicht akzeptabler Bildqualität führen. Ersatzlampenmodule können von Clarity Visual Systems, Inc., bestellt werden. Verwenden Sie nur Projektionslampenmodule, die von Clarity Visual Systems, Inc., oder einem von Clarity Visual Systems, Inc., autorisierten Kundendienstzentrum speziell für den WN-5230-S empfohlen werden. WARNING Do not block the WN-5230-S cooling fan or free air movement under, over, or around the WN-5230-S. Loose papers or other objects should not be nearer to the WN-5230-S than 6 inches on any side. CAUTION Air handling ducts can discharge unwanted dust or hightemperature air directly on the display. Do not operate the WN5230-S in dusty or high-temperature conditions. CAUTION Where several WN-5230-S displays are combined vertically, installation requires a minimum of 12 inches of clearance above the top row, if the top units will be installed from the front. CAUTION Some types of environmental lighting, such as incandescent, or high-intensity discharge lamps such as metal halide or mercury vapor lamps create high temperatures. This can cause excessive heating of the WN-5230-S VideoWall. The WN5230-S VideoWall installation should be positioned away from lighting to prevent heat buildup. CAUTION The front screen of the WN-5230-S VideoWall can be easily scratched and the optical quality degraded by fingerprints. Install the WN-5230-S VideoWall in such a way that it is not exposed to touching or possible scratching by hard objects. CAUTION The Ultra-Thin Mullion screen units are not serviceable from the front. 7 Clarity Visual Systems Quick Start This is a brief sequence of actions that must be followed to properly setup the WN-5230-S. Complete instructions and explanations of the steps are contained in the following chapters. 1 2 3 4 5 6 7 8 Remove the screens and build the wall starting with the lower row. Bolt the displays together side-to-side. If you have Ultra-Thin Mullion screens, align the displays and their adapter plates. Replace the screens. Attach the power cable and video/data cables to the rear connector panel. Connect the video/data cables to the source. Plug the power cable into the wall outlet or other suitable power source. Remember that each display can draw as much as 1.7 amps at 115 volts (0.9 amps at 230V). Turn on the display’s main AC power switch and wait for the 30 second standby-delay to elapse. The lighted power switch indicates when AC power is applied and the switch is on. After the 30 second standby-delay has elapsed, press the remote control’s ON button to turn-on the display. Select the SOURCE in the menu. Use LEVEL ADJUST to calibrate the display to the source. Always adjust black before white! Display a black image from the source and auto-adjust the BLACK LEVEL. Display a white image from the source and auto-adjust the WHITE LEVEL. 8 September 1999 WN-5230-S VideoWall User’s Guide 9 10 11 12 13 14 Select (or deselect) SHARPNESS in the Misc Control menu. Display a checkerboard pattern (alternating black and white pixels) from the data/video source and adjust the FREQUENCY. This step is most applicable to computer sources.

At 200 Watts the current draw is approximately 1.7 Amps at 115 VAC (0.9 Amps at 230 VAC). Voltage Range The WN-5230-S will operate between 100 and 240 volts AC at 50/60Hz. Since the power module is auto ranging, there is no manual selector switch. The main power switch on the power module also acts a circuit breaker. If power to the display is lost, check the power/breaker switch by turning it off and then back on. The power switch is a lighted switch. When it is lit, it indicates that the AC power is applied and the power switch is on. WARNING Displays that are intended for 240V configuration must have a properly rated power supply cord and attachment plug supplied by the installer. WARNING If extension cords are used for power, ensure that only 3-prong grounded cords sized to handle system power requirements are used. Using the wrong-size extension cord can cause a firesafety hazard and can reduce the voltage available to the WN-5230-S. If the extension cord is warm to the touch it is too small and should be immediately removed from operation. WARNUNG Falls für die Stromversorgung Verlängerungskabel benutzt werden, achten Sie bitte darauf, daß nur geerdete, dreipolige und für die vorgesehene Leistungsaufnahme ausgelegte Netzkabel benutzt werden. Die Verwendung eines unterdimensionierten Verlängerungskabels stellt eine potentielle Feuersgefahr dar und kann dazu führen, daß die für den WN-5230-S Video-Monitor verfügbare Spannung zu gering ist. Falls das Verlängerungskabel sich fühlbar erwärmt, heißt das, daß das Verlängerungskabel unterdimensioniert ist. Es muß dann sofort aus dem Verkehr gezogen werden. WARNING Hazardous voltages inside the display and power module can shock, burn and cause death. Only the WN-5230-S lamp and air filter are user serviceable. Always turn off and disconnect power before servicing these items. Refer all other service to a qualified service center. Failure to do so could result in electrical shock, ultraviolet radiation burns, contact heat burns, serious injury, or irreparable damage to the WN-5230-S and may void your factory warranty. 11 Clarity Visual Systems WARNUNG Im Innern des Monitors liegt gefährliche Hochspannung an. Falls Sie unter Hochspannung stehende Teile berühren, können Sie einen elektrischen Schlag erhalten bzw. Verbrennungen oder sogar den Tod erleiden. Im Innern befinden sich keine Teile, die von einem Laien gewartet oder repariert werden könnten. Überlassen Sie alle Wartungs- und Reparaturarbeiten einem qualifizierten Techniker. Temperature and Humidity The WN-5230-S is designed to operate over an ambient temperature range of 0° to 35° C (32° to 95° F) and between humidity of 20 to 80 % R.H. noncondensing. The air that cools the display and the warm exhaust air is passed through the back of the WN-5230-S. This area should not be blocked. If the display becomes overheated, permanent damage to the product may result. Some types of environmental lighting, such as incandescent, or high intensity discharge lamps such as metal halide or mercury vapor lamps, create high temperatures and this can cause excessive heating of the WN-5230-S. The displays should be positioned far enough away from high-temperature lights to prevent heat buildup. Nearby heat sources can cause high operating temperatures in the WN5230-S. Minimize the display’s exposure to heating ducts, radiators, or other external heat sources. Flooring A typical WN-5230-S weights approximately 120 lbs. (55 kg). Before installing the WN-5230-S, determine the structural integrity of the flooring where it will be used. The floor should be level and strong enough to support the combined weight of the number of displays and other equipment used in the installation. Take special care when installing a WN-5230-S in a wall configuration on a temporary structure such as a stage floor, where the flooring could bend or collapse under the weight of the installation. The maximum number of WN-5230-S’s stacked vertically in a wall configuration resting on a temporary floor should be no more than 4. Clearance Normal maintenance, such as lamp and air filter replacement, can be performed from either the front or rear of the WN-5230-S. However, the units with Ultra-Thin Mullion screens are serviceable only from the rear. A minimum of 4 feet of clearance is recommended for easy front access and for easy rear access a minimum of 3 feet is recommended. 12 September 1999 WN-5230-S VideoWall User’s Guide To allow proper cooling, the minimum required clearance to the rear of the Unit is 4 inches. If installed in a video wall configuration, a minimum of 12 inches to the ceiling from the top of the highest display is needed if the units are installed from the front. Cables and Signals Video connections from the signal source to the display depend on the type of signal supplied by the source. The compatible data inputs are: PC 800x600 (SVGA), PC 640x480 (VGA), MAC 800X600 or 640X480, 31.5 kHz and 15.75 kHz (progressive scan) RGBS video, composite video, and S-video. The Loop-Thru video output uses a standard 15 pin VGA type connector for output to an external computer monitor or to another WN-5230-S. The format of the Loop-Thru video is same as the source video. The video cables used should be high quality and shielded to insure the best image quality when displayed. VGA and MAC will have RGB with separate HSync and V-Sync. RGBS video will come out RGBS with the composite sync on the connector’s H-Sync pin. RGB Sync on Green sources will loop-thru RGBS-Sync on Green. Displays with the VIM-300 option also have Composite Video and S-Video loop-thru connectors. Using poor quality cables can lead to picture noise, jitter and crosstalk. Even good quality cables that are longer than 10 feet may produce noise and jitter in the image if the source signals are not amplified. Control data enters the display via the RS-232 In connection, and is supplied to an adjacent display (if used) via the RS-232 Out connector. High quality shielded cables designed for RS-232 communication should be used to ensure proper data transmission and control. The wiring of the RS-232 cables must be straight through (pin 1 to pin 1, pin 2 to pin 2, etc…) and not wired for “null modem”. 13 Clarity Visual Systems Optical Alignment Tools Required: 3/32 inch Allen-hex driver 3/8 inch socket driver Optical Alignment means to the adjust the size and position of the image and to correct for keystoning and rotation. Before installing a display, check it to verify that the image is optically aligned. When thinking about the optical calibration process, here are some things to remember: • The critical dimension during calibration is the distance from the projection lens to each corner of the screen. If these distances are equal, from lens to mirror to screen, the image will be a rectangle. • The light path from lens to screen is expanding. If the path of one corner is a little longer, that part of the image will expand more; if shorter, that part will be smaller. • Work on one thing at a time and in this order: 1. Make the image rectangular. Don’t worry at first about size or placement. Just make it have four square corners. 2. Adjust rotation, so that the edges of the image are parallel with the edges of the screen. 3. Adjust size, making the image fill the screen. In standard mullion screens, this means hiding three pixels behind each mullion. With Ultra-Thin Mullion screens, hide one pixel at each edge. 4. Adjust position, left and right, up and down. • 14 In most cases, only slight adjustments are required, usually just position. Don’t try to adjust anything that doesn’t need it.

Optical Engine, right side. 16 September 1999 WN-5230-S VideoWall User’s Guide For an image that is way out of alignment and that needs major adjustment, start with everything in a “normal” position: • If the screen is Ultra-Thin Mullion, remove the screen and check that all the pointed alignment bolts are at the same distance. Put the shipping shim behind each bolt and tighten the bolt to it. (Later, when building a wall, make sure that the main chassis of the cubes are aligned. It is a mistake to move the screens in and out a great distance with the pointed alignment bolts to compensate for main chassis that are not even with each other. Moving these bolts a lot will change the image size, because the lens-to-screen distance changes.) • Each corner of the optical engine mount should start at the same distance out. Factory default is 3 cm, but any distance near this amount will do a good job. Make a block of wood that is 3 cm thick and use it as a gauge at the four corners of the metal engine mount. Then adjust S1, 2, 3, and 4 to make the engine mount just touch the block. • Adjust the lens screws, LS1 and LS2, so they are part way in. As these screws turn out, eventually they reach a point where the spring no longer pushes the lens toward the screw. Have the lens in a middle position, so that the spring is pressed some, but not as much as half way. Adjusting the Image There are four nuts on the engine mounting plate, S1, S2, S3, and S4. Adjust these in pairs and turn them equal amounts. Figure 1. Optical engine, seen from rear, showing location of four “S” adjustment screws. Figure 2. Diagram of optical engine, mirror and screen as seen from the side. 17 Clarity Visual Systems Keystone, top wider To fix this, loosen nuts S1 and S3 in equal amounts to make the top smaller. This will lower the image on the mirror, shortening the distance to the screen for the top, thus making it smaller. The whole image will be lowered, but you can fix this later with the lens adjustment. Keystone, bottom wider To fix this, tighten nuts S1 and S3 equal amounts to make the top larger. This will also raise the image, so you will have to use the lens adjustment later to lower it. Keystone, left side wider To fix this, loosen the lock down nuts, LD1 and LD2. Then loosen N1 or tighten N2. Retighten LD1 and LD2. Keystone, right side wider Loosen the lock down nuts, LD1 and LD2. Then tighten N1 or loosen N2. Retighten LD1 and LD2. Rotation, clockwise Loosen S3 and S4, or tighten S1 and S2, equal amounts to rotate the left side of the image down.

The WN-5230-S comes with either a standard screen, an Ultra-Thin Mullion Screen, or a Blackscreen™. (Blackscreen has the same dimensions as the Ultra-Thin Mullion.) • The standard screen has a mullion about 1/8 inch (3 mm) wide. The mullion is a strip of sheet metal surrounding the screen and holds it in place. • The Ultra-Thin Mullion Screen, or mullionless screen, does not have the 1/8th inch strip of metal around the screen. The edge of the screen goes right to the edge of the display unit. This makes the lines between display units much less apparent in the finished video wall. • BlackScreen™, a mullionless screen as above, but with a higher contrast ratio. th Mechanical Setup, Standard Screen Install the WN-5230-S in the desired position and connect the power and signal cables. See the following section for an explanation of the cabling configuration. Figure 3 Connecting display units 22 September 1999 WN-5230-S VideoWall User’s Guide To setup the WN-5230-S display in a video wall configuration, follow these steps: 1. Grasp the screen on each side at the bottom The “screen” you are removing is 5 inches thick. Pull out at the bottom first, to separate the latch-hooks from the latches. It comes out with a “pop.” The screen should now be loose at the bottom, but still attached at the top. 2. Slip fingers between the screen frame Slip fingers between the screen frame and the display chassis, as close to the top latches as possible and pull the top of the screen from the latches. 3. Using both hands… Carefully remove the screen and set it aside. 4. Assemble the lower row first. Line up the legs for the bottom row as straight as possible. Insert a ¼” X 2 ½” bolt through the holes as shown at the bottom of Figure 1. Tighten a nut securely on this bolt, but take care not to bend the legs. Secure the legs to the floor. Use the tapped 5/16-18 holes in the front and rear of the legs. You can put an eye-bolt in this hole and secure it to the floor with a lag screw. Or use angle bracket, screwed to the floor and bolted to this hole in front and rear. Or use the optional BAS-520 base, securing it to the floor and putting the lower row of displays on it. Before going to the next higher rows, see that the bottom row is straight. From one end of the line, look along the front of the displays. The line should be straight and flat. Level is not as important as straight and flat. 5. Stack the next higher row. Slide the legs of each display into the mating sockets of the display in the first (lower) row. Check it for “straight and flat.” 6. Insert a bolt (supplied). Insert a bolt through the hole in side wall of the lower unit into each leg of the unit above. Tighten a nut on this bolt to lock the units together. See Figure 1, above. 7. Continue with subsequent rows of displays Lock each display to the adjacent displays after the row above it (if any) has been installed. Bolt the top row together, even though there are no legs from a higher row. 8. For added stability… Use the rear-tapped holes in the legs of the upper units to fasten to a solid support, such as a structural wall. The threaded inserts in each leg are female 5/16-18 UNC. 9. Check Check that all displays in the video wall are locked together. Look again down the line from one end to see that each row is straight and flat. 23 Clarity Visual Systems 10. Reinstall screens Reinstall each display’s screen. Mechanical Setup, Ultra-Thin Mullion or Blackscreen CAUTION The displays with Ultra-Thin Mullion screens are not serviceable from the front. Service should be performed through the rear access cover. Instructions for BlackScreen are the same as for Ultra-Thin Mullion screen. You will need these tools: • a large, flat blade screwdriver • an SAT-500 Screen Alignment Tool (two of these tools makes installing a video wall even easier.) • black cloth tape • a tape measure (inches or centimeters) • 1/2” open-end wrench, a 1/2” deep-well socket, or an adjustable wrench • 5/64” Allen hex wrench The thin mullion display screens consist of two basic parts. There is the screen itself and the frame it is held in, an assembly which is about 3” (7 cm) thick. The screen attaches to the second part, an adapter plate which is about 2” (5 cm) thick. The adapter plate is mounted on the front of the display unit. Retaining screw Finger hole Space Adapter Plate Thin Mullion Screen Figure 4 Ultra-Thin Mullion Screen 24 September 1999 During the alignment process, you remove the screen from the adapter plate, then adjust the adapter plate to make its corners square and align correctly with its neighbors. Then the screen is re-installed and adjusted in or out. Installing a video wall with Ultra-Thin Mullion Screens is a little more complex than installing the wall with standard mullion screens. Mechanical alignment is more critical, and the larger the video wall, the more precisely each unit must be aligned to produce a good looking image. The outcome of this alignment process is partly dependent on how flat the floor is, but it is mostly dependent on how tightly the displays are fitted to each other. WN-5230-S VideoWall User’s Guide Basic Steps for Alignment This is a summary of the steps necessary to build a video wall thin mullion displays and align their screens. This is a summary only. The details on how to perform each step follow the summary. 1. Remove the screens from all the display units. 2. Build the video wall. 3. Start with the display unit in the center of the bottom row. Square its adapter plate. 4. Using the Alignment Tool, working along the bottom row in both directions from the squared adapter plate and align each of the other Adapter Plates to its neighbor. 5. Align the adapter plates on the rest of the rows, working upward, to the adapter plates in the bottom row. 6. Hang the screens on the bottom row and adjust them in or out so the front surfaces (the screen faces) are flat with each other. Then do the rows above. 7. Put retaining screws in the top row and cover any holes and seams with black tape to prevent light leaks. Alignment Procedure in Detail Read through all the detailed parts of each numbered step before starting it. 1. 2. Remove the screens from all the display units. Build the video wall. A. Look down on the top of the screen and locate the two retaining screws. Remove these screws, using the 5/64-inch Allen hex wrench, and set them aside. B. Grab the sides of the screen, or use the finger holes, and lift it up about half an inch (1 cm), and remove it from the adapter plate. Set it aside. A. Assemble the lower row first. Line up the legs for the bottom row as straight as possible. Insert a ¼” x 2½” bolt through the holes as shown in Figure 1. Tighten a nut securely on this bolt, but not so tight as to bend the legs. From one end of the bottom row, look along the row to see that all the units are aligned, that the line of the front of the display units does not curve forward or backward, up or down. The straighter the first row, the better the finished wall will be. And the easier it will be to keep it straight as you build. B. Secure the legs to the floor. Use the tapped 5/1618 holes in the front and rear of the legs. You can put an eye-bolt in this hole and secure it to the floor with a lag screw. Or use angle bracket, screwed to the floor and bolted to this hole in front and rear. Or use the optional BAS-520 base, securing it to the floor and putting the lower row of 25 Clarity Visual Systems displays on it. (If the BAS-520 is used with UltraThin Mullion screens, remove the adapter plate before you put the unit on the base.) Stack the next higher row. Sliding the legs of each display into the mating sockets of the display in the first (lower) row. 3. Start with the display unit in the center of the bottom row. This will be the Base Unit. Align the Base Unit’s adapter plate. (If the bottom row has an even number of display units, choose either middle one. This step can be done before the wall is built, if necessary.) 26 September 1999 C. Insert a bolt (supplied). Insert a bolt through the hole in side wall of the lower unit and into each leg of the unit above. Tighten a nut on this bolt to lock the units together. See Figure 1 above. Tighten all the bolts after you have checked for straightness, as in Step A above. D. Continue with higher rows of displays. Lock each display to the adjacent displays after the row above it (if any) has been installed. Check for straightness on each row. E. For added stability, use the tapped holes in the rear of the legs of the upper units to fasten to a solid support, such as a structural wall. The threaded inserts in each leg are female 5/16-18 UNC. F. Check that all displays in the video wall are locked together. And straight. A. Look at the sides of the Adapter Frame. (See Figure 3, below.) Starting at the top edge and moving down you will see a large Locking Screw, a pointed Alignment Bolt, and an Alignment Hole. Near the middle of each side is a threaded hole for the Alignment Tool’s spring-loaded screws. (Do not attach the Alignment Tool yet.) At the bottom of the side notice the Alignment Hole, the Alignment Bolt, and the Locking Screw. B. Look at all the Alignment Bolts of all units. They should all be the same distance out. The factory ships the display with a “shipping shim” behind this bolt. If you have to adjust these bolts, you should remove this shim. Save it. Use it later, if you need to ship the units. When you ship UltraThin Mullion screen displays, always have the Alignment Bolt either tighten onto the shipping shim, or tighten down completely. C. Check to see that the Adapter Frame of the Base Unit is centered on the chassis. If the frame is not centered on the chassis opening, for instance, if it is offset to the left, then all the other frames will have to be offset in this same direction. It is best if this first frame is nicely centered on its chassis opening. D. Check to see that all the Locking Screws are tight. E. Measure the opening diagonally, from corner to corner in both directions, and compare the results. Be sure to measure from exactly the nd same points each time. An accuracy of 1/32 inch (0.8 mm) is necessary for most applications, but the more accurately you can do this, particularly in the bottom center unit, the better the video wall will be aligned and the better the WN-5230-S VideoWall User’s Guide picture will look. F. If the two measurements are the same, you have a rectangle with perfectly square corners, and you may go on to Step 4. G. If the two measurements are not the same, within nd 1/32 inch (0.8 mm), the frame is not a rectangle with perfectly square corners, it is a parallelogram. Loosen the top Locking Screws on each side. Move the adapter plate left or right a bit and tighten the screws. Measure the diagonals again. Repeat this process until you are satisfied that the two diagonals are the same. This means the adapter plate is a perfect rectangle with square corners. 4. Working along the bottom row in both directions, align each of the adapter plates, using the Alignment Tool. A. Now that the center unit adapter plate is squared, align one of its neighbors in the bottom row. 8 5 9 6 4 7 2 1 3 B. The diagram above shows the order in which you should align the displays in a typical video wall. (Note: This is not the same as the Unit ID address of the display units.) C. The Alignment Tool fits over the seam of two adjacent adapter plates. The Tool has six guide pins, three on each side, and four spring-loaded screws, two on each side. (Only two of the springloaded screws, one on each side, will be used at a time.) D. Position the Alignment Tool between the two displays. One of these (#1) is already square and the other (#2) is about to be aligned. Fit the tool into display #1 first and attach it with the lower spring-loaded screw. The guide pins should go into the Alignment Holes in display #1. E. Loosen the two Locking Screws in #2 on its right side under the Alignment Tool and move the adapter plate of display #2 until the guide pins go in the Alignment Holes. Secure the Alignment Tool to #2 with the spring-loaded screw. Tighten the two Locking Screws on #2 under the Alignment Tool. (Do not be concerned about the 27 Clarity Visual Systems units in the row above at this time.) F. With the Alignment Tool still in place, check display #2 for squareness by measuring the diagonals. Loosen the Locking Screws on #2 that are on the other side from the Alignment Tool, and adjust adapter plate #2 until it is squarecornered rectangle. G. When you are satisfied that display #2 is aligned to display #1 and it has perfectly square corners, remove the Alignment Tool. (If you have two Alignment Tools, leave this first one in place, and put the second on the other side.) 5. 6. Align the adapter plates on the units above the Base Unit, working upward. Hang the screens on the bottom row and adjust them in or out so their front surfaces are flat with each other. H. Go to the display on the other side of the center display (#3) and align it to the center display, following the steps 4.C through 4.G. A. Start with the display above the Base Unit. Align display #4 to display #1. Put the Alignment Tools on either side of the Base Unit, #1. The upper guide pin should now fit the bottom Alignment Hole of #4. Loosen the bottom Locking Screw in #4 and make it fit. Do the same on the other side, moving the Alignment Tool, if you have only one. B. Measure the diagonals of #4. Loosen the top two Locking Screws and make its corners square, then tighten the screws. C. Continue with display #5, working your way up the video wall to the top. D. When you have completed the inverted-T, use these as a frame and align the other units to it, working from the lower rows upward. For each display, you should be sure it is the correct distance vertically and horizontally from all its neighbors and that each unit’s diagonals are equal. A. Hang the screens on the bottom row. Be sure the finger holes are on the top of each screen. When each screen is seated, pull on it slightly to make sure it is secure at both the top and bottom. B. Notice the seams. Are the two screens flush at each seam? If not, note how much you will have to adjust one of the screens to make it flat and flush with its neighbor. Measure this amount, but be careful not to scratch the screens. Also, sight along the row from the end. Look down the groove on the top of the screens. This helps to prevent where the corners match, but the screens are not flat. Make a diagram of the video wall and note how far to move each corner of each unit in or out. Try to get the wall flat within 1/32” inch (0.8 mm) 28 September 1999 C. Remove the screens again. D. Working from your notes, adjust the pointed Alignment Bolts with the ½-inch wrench. Looking at the display from the front, each complete turn of the bolt CW (clockwise) pulls the corner of the WN-5230-S VideoWall User’s Guide screen IN (away from you) by 1/32nd of an inch (0.8 mm). 7. Put retaining screws in the top row and cover holes and seams with black tape to prevent light leaks. E. Hang the screens again and check your work. F. With the screens in place on the bottom row, put the screens on the next row above. “Flatten” this row in the same way, paying attention to how these fit with the bottom row as well as with their neighbors to the left and right. A. When all the screens are aligned with each other to make a flat, square video wall, put the screws in the top row of screens to hold them in place. B. The finger holes and the space between the screen and the adapter plate can be a source of light leaks, allowing stray light to hit the back of the screen and wash out some of the picture. To prevent this, cover the finger holes in the top row of displays with black cloth tape. “Gaffer” tape does a nice job of this. Masking tape is sometimes difficult to remove cleanly. You can check for light leaks during the video setup process. Select “Curtain” from the main menu and verify that the whole screen is black. It is best to do this in the actual lighting that will be on when the wall is used. 29 Clarity Visual Systems Locking Screw Alignment Bolt Alignment Hole Hole for SpringLoaded screw Alignment Hole Alignment Bolt Locking Screw 30 September 1999 WN-5230-S VideoWall User’s Guide 31 Clarity Visual Systems Operation After the displays are installed, use these procedures: Step 1 - Power-On Step 2 - Adjust the Input Signal Settings Step 3 - Adjust the Colors Step 4 - Save the Settings Step 1 – Power-On 1. Turn the main power switch on the power supply to the ON position The Standby LED flashes, indicating the power up cycle has begun. Wait approximately 30 seconds until the Standby LED is on and not flashing. 2. Press the remote control ON button to power up each Display You will hear a ‘beep.” The lamp will come on, but it will require a few minutes to fully warm up. There is a built-in delay from when you press the remote’s ON button to when the lamp starts to ignite. The extent of the delay depends on the position of the Unit switch on the rear panel. GROUP ID numbers are 0-9 and A-F for a total of 16 different settings. Each number is equal to that number times 16. A setting of 3 is equal to 48. UNIT ID numbers are 0-9 and A-F for a total of 16 different settings. Each number is equal to that number times one. A setting of C equals 12. The Monitor ID number is the combination of the Group ID plus the Unit ID. A Group ID number of 2 and a Unit ID number of 5 equals a Monitor ID of 37 decimal, 25 hexadecimal. The delay time between an “on” command to the display and the ignition of the lamp is approximately 1 seconds times the Unit ID number. 3. 32 Check for normal September 1999 Observe the LED on the rear of each unit. When the WN-5230-S VideoWall User’s Guide operation electronics “thinks” the lamp is on, the STBY LED is off, and the fan and lamp LEDs are on. However, the electronics does not know whether the lamp is actually lit. A faint glow from the lamp exhaust vent in the rear of the unit indicates the lamp is on.

Highlight the [ ] next to Auto and press ENTER. Auto takes information from H Freq, Lines, and V Freq, shown at the bottom of the menu, and sets the image size and refresh rate. Auto does this just once. The X will appear in Auto for a very brief moment. For computer sources, always use Auto rather than selecting the Mode manually. Note: PCs sometimes produce a 400 line video signal. This happens when Windows boots up or when the PC has a fault and shows a fault message. During this time, the display will roll, because it does not recognize 400-line video and can’t sync to it. If this happens, and you have no other way to see the video output of the computer, press Source on the remote control. Then highlight Auto and press Enter. The display will now recognize and show the 400-line video image. (This mode cannot be saved in memory.) After the PC’s problem is fixed, use Auto again to reset the input mode. 34 September 1999 4.

V Freq: Shows the frame rate of the displayed signal. You can’t change this value. WN-5230-S VideoWall User’s Guide Input Level When the black and white levels are correctly set, the display will know what the absolute minimum and maximum signal amplitude is that the source is sending to it. The procedure for Input Level adjustment, and the menus for it, are different for computer sources and video sources. You must adjust input level for each source that is connected to the display. Even if two similar sources are being used, such as two different SVGA sources, the input levels must be adjusted for the source that is connected at this time. When the other SVGA source is connected, the levels must be readjusted to match the new source. If the sources are connected to different inputs (SVGA, MAC, RGBS) then each source’s Level can be set and saved separately in memory, because there is a different memory for each source-mode combination. For all sources except composite and S-video, the input Black Level must be adjusted to match the source before adjusting the input White Level. Note: Do not use Black Level Adjust and White Level Adjust to color balance the displays. Matching the displays so they all produce the same colors is done in a later step called Color Balance. Color Balance and Level Adjust are entirely independent of each other. Level Adjust must be done with external video signals. Color Balance should be done with internally generated patterns. 35 Clarity Visual Systems Adjust the Black Input Level - PC, MAC or RGBS Data (This does not apply to Composite or S-Video sources – see Comp Video/S-Video Level Adjustment on page 38.)

Selecting the Lock feature causes the image to scale the same amount in the opposite direction. If you scale the Right, the Left will scale by the same amount. Similarly, Up and Down The Default feature scales the image back to 800x600 or 640x480 pixels, depending on the source, or to some other values, depending on the Big Picture scaling. Step 3 - Adjust the Colors Note: It is a good idea to read this whole section before you start color balancing. Source Select Frequency Phase Input Level Position Zoom Wall Processor Color Balance Curtain Hours Save Config Recall Config Reset Config Misc Control About Color Balance Wht Gry #$ #$ All Red 031 007 Green 031 007 Blue 031 007 Color balancing compensates for the differences in brightness of all display units in a video wall. You only need to do this once, as color 46 September 1999 WN-5230-S VideoWall User’s Guide balance is the same for all sources. The color balance information is saved in memory in only one location, not for each source. However, when a lamp is changed, you should color balance again. The goal of color balancing the displays is to match the brightness and white “color” of all the displays in video wall to each other, and then match the intermediate gray shade. Therefore, color balancing is accomplished with all displays turned on in the finished video wall. (If you have only one unit, color balancing is not very important.) Do not start color balancing until all lamps have been on for at least five minutes. The color balance menu provides control over the individual RED, GREEN, and BLUE settings to balance the white color, as well as an ALL adjustment to control the overall luminance by changing all three colors together. Similar control for the RED, GREEN, and BLUE settings is provided to adjust the balance of the gray shades without affecting the white balance. The down arrow key moves the cursor from All to Red, Green, and Blue in the White column, then to All, Red, Green, and Blue in the Gray column, then back to All in the White column again. The left/right arrow keys increase and decrease the brightness number. It is a common mistake to use the left-right arrow buttons to try to move the cursor between columns. Doing this simply changes the currently selected value. For white balancing, the individual RED, GREEN, and BLUE color selections have a number between 0 and 31. Zero is the darkest and 031 the brightest. For gray balancing, the individual RED, GREEN, and BLUE balance settings have a number associated with them between 0 and 7. Zero is the darkest and 007 the brightest. The following chart shows the relationship of the menu item adjustments. Color All Red Green Blue Increase will: Decrease will: Increase the overall luminance (brightness) Decrease the overall luminance (brightness) Change white toward red Change white toward cyan Change white toward green Change white toward magenta Change white toward blue Change white toward yellow Note: If one color needs to be increased, but that color is already as high as it can go, then the other two colors can be decreased. 47 Clarity Visual Systems Use the White and 50% Gray internal Test Patterns from the Misc Control menu, not an external pattern. 1. Display an all-white image On each display in the video wall, open the Misc Control menu, select Test Pattern and choose White. 2. Open the COLOR menu Press the Color button on the remote control, or choose Color Balance from the main menu and press Enter. 3. Maximize all settings Adjust the WHT setting of all the displays to 031; adjust the GRY setting of all displays to 007. 4. Identify the leastbright display in the system The least bright display is already as bright as it can be. This display will serve as a baseline to which the other displays will be adjusted. Note: The baseline display does not have to be the middle one. It should be the darkest one, wherever it is in the wall. The darkest display is called the “baseline” display. 5. Luminance match the displays Select one of the displays next to the baseline display. This will be called the “variable” display. Turn off the Color Balance menu to all displays except the variable display. In the Color Balance menu on the variable display, highlight the arrows under the Wht. Use the left arrow to reduce the brightness until the variable display is the same brightness as the baseline display. 6. Color balance the displays – white mode On the variable display, adjust the amounts of RED, GREEN, and BLUE in the white (Wht) column to achieve the best match in color and luminance to the baseline display. If a color needs to be increased, but that color is already as high as it can go, then the other two colors can be reduced. For instance, if you need the white to be have more red, but red is already at 031, reduce the green and blue. This will make the display look more red. 7. Adjust the next display When the variable unit matches the baseline, in can serve as a new baseline unit for its neighbors. Continue to work outward from the original baseline display, one cube at a time. Do not go to the next step of adjusting for Gray until you are satisfied that all the displays look the same for a white image. It is not important to obtain pure white; it is only important that all the displays look the same. 8. Display a 50% gray image On each display in the video wall, open the Misc Control menu, select Test Pattern and choose 50% Gray. 9. Identify the least bright unit again Find the unit that looks the darkest. This may not be the same one that was the darkest one with a White test pattern. This is the baseline unit for Gray. 10. Color balance the displays – 50% gray mode Using the same technique of adjusting a variable display to the baseline display, match the color and brightness of all cubes, working with one cube at a time and working outward. A helpful technique to use when adjusting the colors and gray shades is to “overshoot” as you adjust to emphasize the effect that the current adjustment 48 September 1999 WN-5230-S VideoWall User’s Guide is having to the overall image. Then back off to fine tune. This helps to give an intuitive feel for the color balance process. It is often helpful to switch between the internal white and gray patterns and actual video images to fine tune the system. Avoid making major changes when adjusting to the video images because this can throw off the white or gray balance. Remember also that the Input Level adjustment has a large effect on color. If Input Level adjustments have not been made, color balance for live video will be difficult. However, you may adjust Color Balance before or after you do the Input Level adjustment. They do not affect each other – that is, an adjustment in Color Balance does not affect the Input Level adjustment, and vice versa – but they must both be adjusted properly for the screens in the cube to match in color, luminance and black level. Do not adjust Color Balance with Red, Green and Blue test patterns. This is a method sometimes used with CRT displays, and it will not work with these Clarity displays. The primary colors have been matched at the factory. If you get the whites and grays to be the same over a whole wall, all the other colors will be the same, too. After you have color balanced all the units, save the settings for each unit. It does not matter which source-mode combination you save, because color balance data is saved once for all sources and modes. You should not have to color balance the displays again until you change a lamp. However, lamps near the end of their life may begin to change color, so it is a good idea to check color balance occasionally. Note: Setting the Gray color balance levels near 004 or 003 will often give improved performance when the primary program source is composite or S-video. To try this, reduce the overall brightness of the gray baseline cube to these levels in the Gry column. Adjust this baseline cube to have the least amount of color in the 50% gray field. Then balance the other cubes to this one. 49 Clarity Visual Systems Step 4 – Save, Recall, or Reset the Settings After all adjustments have been made, Save the settings. There is a separate Save location for each source in each mode – PC at 800x600, PC at 640x480, RGBS at 31.5 MHz, RGBS at 15.75 MHz, etc. After you have adjusted the displays for one source, save these settings before going to the next source and adjusting it.

Big Picture can be setup and saved for each video source, so you can switch between sources while maintaining the specific magnification and position settings for each source. 1. Build the wall Install the wall and attach source and power cables as described in earlier sections. Use an amplifier/splitter device (distribution amplifier) from the source or, if you are using loop-thru, use short, shielded cables to minimize noise and image jitter. 2. Select the Source and Mode In the menu for each display, select the source that will use Big Picture. If this is a computer source, use Auto for Mode selection. 3. Adjust the image settings As described in Step 2, Step 3, and Step 4 in earlier sections, adjust black and white levels for each display; set phase and frequency; color balance the wall. 4. Disable wall mode Open the Wall Processor menu and make sure that the Wall mode feature at the bottom of the menu is not checked. Do this for each display. 5. Reset Zoom Set Zoom in the menu to the default width and height of 800x600 or 640x480, depending on the Source and Mode. 6. Center the image Find the edges of the image using the arrow buttons in the Position menu to move the image. For standard mullions, each mullion covers 3 pixels of the image and each button press in the Position menu moves the image one line or pixel at a time. Move the image so that 3 pixels on each side of the image are behind their respective mullions. For Ultra-Thin Mullion screens, one pixel should hide behind each mullion. When you move the standard size (not zoomed) image, if you find that more or fewer than 3 pixels (or one pixel) are hidden, then the optical image size needs to be adjusted. Do not Zoom the image to accomplish this. 54 September 1999 WN-5230-S VideoWall User’s Guide 7. Set each display’s address (See note below for walls larger than 4x4.) Assign each display a unique address using the Unit ID knob. Both the Group and Unit ID numbers are used The address of the display in the upper left corner (as seen from the front) must be zero. The addresses of the other displays must increase left to right, top bottom, increasing by one for each display. Therefore, the display in the lower right corner (as seen from the front) always has the highest address. 2x2 example $ (Seen from the front) 3x3 example $ 8. Set the Wall Size on each display 00 01 02 03 0 1 2 3 4 5 6 7 8 Open the Wall Processor menu. Enter the horizontal and vertical wall size. Each display’s menu should show the same horizontal and vertical wall size. Each display should show a different Current Unit value. This value represents its location in the wall. Note: Clarity’s Big Picture handles up to a 6x6 video wall. Because the Unit knob only has 16 positions, the Group knob must be used for all walls that have more than 16 displays. A 6x6 wall would be numbered like this (top number is Group; bottom number is Unit): 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 10 11 12 13 14 15 16 17 18 19 1A 1B 1C 1D 1E 1F 20 21 22 23 55 Clarity Visual Systems Source Select Frequency Phase Input Level Position Zoom Wall Processor Color Balance Curtain Hours Save Config Recall Config Reset Config Misc Control About If the display has Big Picture, you will see a menu like this: Wall Processor Wall Size: Horizontal: Vertical: Current Unit: 002 002 01 Misc: [ ] Calc wall pos [ ] Wall mode If this unit does not have Big Picture, you will see a menu like this: The Big Picture option is not installed.

This calculates the position of the selected display within the image and puts the display into Wall Mode. Each display will now show only its segment of the overall image. Do this with each display in the wall and exit the Wall Processor menu. 10. Fine tune the wall image If the previous steps were done correctly, the image in each display should not need to be adjusted by more than two lines or pixels in any direction. If an adjustment to the image must be made, use the Zoom menu to move only the edge that needs adjustment. 56 September 1999 WN-5230-S VideoWall User’s Guide 11. Save the settings Open the Save Config menu and save the settings for the current Source and Mode on each display, as described above in Step 4 – Save, Recall, or Reset the Settings on page 50. If there are other video sources on different input connectors that will use Big Picture, go through the previous process for each video source. Then save these settings. Loop-Thru of Source Video Loop-thru works in different ways depending on the type of source. If the source video is PC or MAC, the same signal is output from the LOOP-THRU connector, which can be connected to the next unit’s PC input. If the source is RGB with separate composite sync at 31.5 kHz (progressive scan), it will come out the LOOP-THRU connector as RGB with the composite sync on the connector’s H-Sync pin and separated V-Sync on the V-Sync pin. Feed this to the next unit’s RGBS connector. It might also work to feed this to the next unit’s PC connector. If the source is RGB Sync on Green at 31.5 kHz (progressive), it will come out the LOOP-THRU connector as RGB-Sync on Green, plus composite sync on the H-Sync output pin, and separated V-Sync on the V-Sync pin. Feed this to the next unit’s RGBS connector. It might also work to feed this to the next unit’s PC connector. If the source is RGBS at 15.75 kHz (interlaced), the output from the LOOP-THRU connector will also be 15.75 kHz. It will not work to loop this output to the next display’s PC input, because the PC input is expecting 31.5 kHz. To loop RGBS at 15.75 to the next display, make an adapter to go from 15-pin to 9-pin using the wiring diagram below. Standard 15-pin-to-9-pin adapters may also be available from some computer stores. Connect the first display’s LOOP-THRU output to the next display’s 9-pin RGBS input. Alternatively, use a 15-pin to 4-BNC adapter cable. These are also usually available from electronics or computer stores. Composite and S-video inputs have their own separate loop-thru connectors. These are buffered. The inputs are terminated in 75 ohms. Using video loop-thru slightly degrades signal quality as the signal goes through each cube. The amount of degradation depends on cable quality, source video, and the number of loops. If this degradation becomes a problem, use a signal splitter or distribution amplifier to directly drive each cube or to at least reduce the number of loops. 57 Clarity Visual Systems Source video RGBS 15.75 kHz 15-pin 15- pin to 9-pin ada pter cabl e 9-pin of "next" display LOOP-THRU connector 1 2 3 13 6 58 September 1999 RGBS connector 1 2 3 4 6 WN-5230-S VideoWall User’s Guide Installing Big Picture Option Key The Big Picture Option Key enables the functions and features associated with Clarity’s Big Picture™.

It is always running, unless power is removed from the whole unit. When you remove the lamp, your fingers may go into the moving fan. Whether you replace the lamp from the front or from the rear, remove the power cord or switch off the power at the power input on the rear panel, before removing the lamp. The WN-5230-S has three screen options: • The standard screen has a mullion about 1/8 inch (3 mm) wide. The mullion is a strip of sheet metal surrounding the screen which holds it in place. • The Ultra-Thin Mullion Screen, or mullionless screen, does not have the 1/8th inch strip of sheet metal around the screen. The viewing area of the screen goes right to the edge of the display unit. This makes the lines between display units much less apparent in the finished video wall. • Blackscreen, like the Ultra-Thin Mullion screen, but looks black when no signal is applied. th With standard screens, electrical interlocks prevent operation when the front screen is removed. Do not operate the display with any access 66 September 1999 WN-5230-S VideoWall User’s Guide panels or the front screen removed from the unit, except when required for servicing. Operating the display with access panels or the front screen removed can expose service or operating personnel to ultraviolet burns and high electrical voltages. Always wear ultravioletblocking eyewear with side guards when servicing the display. For Standard Screens, removing the screen provides service access to other replaceable modules from the front of the display. Service access for units with Ultra-Thin Mullion Screens is from the rear only. Lamp Replacement, Front, Standard Mullion Screens CAUTION For the standard screens, with the wider mullion, the screen may be removed by hand from stand-alone displays without damaging the screen. Where screen edges are adjacent to each other in a video wall, removing the screen without a screen removal tool may damage the female part of the screen latch. In video wall configurations, use the SRT-100 Screen Removal Tool (see instructions below and Options on page 2) to prevent damage to the screen. Follow these steps to remove the standard, wider mullion screen and replace the lamp, if the display unit is not built into a video wall. Read all the steps before starting. 1. Turn off the power Switch off the WN-5230-S using the remote and allow the cooling cycle to complete (30 seconds) before switching off the AC power at the rear-panel switch. 2. Unplug power cord Important: Remove the AC power cord from the display. 3. Grasp the screen on each side at the bottom The “screen” you are removing is 5 inches thick. Pull out at the bottom first, to separate the latch-hooks from the latches. It comes out with a “pop.” The screen should now be loose at the bottom, but still attached at the top. If the display unit is part of a video wall, see Note below about screen removal tool. 4. Slip fingers between the screen frame Slip fingers between the screen frame and the display chassis, as close to the top latches as possible and pull the top of the screen from the latches. 5. Using both hands… Carefully remove the screen and set it aside. 6. Open the projector compartment hood There are two spring latches on the projector compartment hood. Pull these latches towards each other and pull the hood towards the front of the display to open it. 7. Remove the lamp access door On the left side of the optical engine is the lamp access door. Pinch the latch to open and remove the door. 67 Clarity Visual Systems 8. Detach the lamp cable Using your thumb and middle finger to unlock the lamp cable connector, use your index finger to pull the connector away from the lamp. The lamp cable will remain connected to the optical engine. 9. Remove the lamp 10. Install the new lamp and reassemble the display Push the lamp to the right (into the optical engine) while turning counterclockwise. The lamp will rotate about an eighth of a turn, and then it can be pulled to the left (out) and removed. Reinsert a UHP 100W lamp in the same orientation. Push the lamp in and rotate the lamp clockwise until it locks into place. When attaching the lamp cable, pinch the connector clamp together while inserting the connector. The connector is keyed so it will only go on one way. Replace the lamp access door on the optical engine. Close and latch the projector compartment hood. 11. Reinstall Reinstall the screen by lining up the latches and pressing the screen inward. It will go in with a distinct “pop.” Give it a slight pull to see that it is securely in place. Removing a Standard Screen Using the Screen Removal Tool 68 1. Find the bumps on the side mullions On both sides of the screen, near the top and bottom, the mullion is slightly lifted from the screen material, forming a little bump. The removal tool fits here. 2. Insert the removal tool The small hook on the removal tool slips under the bump in the mullion. The other side of the tool should press against the mullion of the neighboring screen. Use care when using the tool so it doesn’t scratch the screen material. 3. Squeeze the handle of the SRT-100 Squeezing the handle of the removal tool pulls one screen out far enough to let it “pop” out at that corner. The tool uses the neighboring screen for leverage. 4. Repeat for all four corners Remove the screen carefully and set it aside. September 1999 WN-5230-S VideoWall User’s Guide These 2 parts push against the mullion of the neighboring screen. This hooks under the bump in the mullion Figure 6 SRT-100, Screen Removal Tool Lamp Replacement, Rear Access, Any Screen Type 1. Turn off the power Switch off the WN-5230-S using the remote and allow the cooling cycle to complete (30 seconds) before switching off the AC power at the rear-panel switch. 2.

Remove the lamp access door On the right side of the optical engine is the lamp access door. Pull on the latch to open and remove the door. 5. Detach the lamp cable Using two fingers to unlock the lamp cable connector clamp, use a third finger to pull the connector away from the lamp. The lamp cable will remain connected to the optical engine. 69 Clarity Visual Systems 6. Remove the lamp Push the lamp to the left (into the optical engine) while turning counterclockwise. The lamp will rotate about an eighth of a turn before it can be pulled to the right and removed. 7. Install the new lamp and reassemble the display Reinsert a UHP 100W lamp in the same orientation. Push the lamp in (to the left) and rotate the lamp clockwise until it locks into place. When attaching the lamp cable, pinch the connector clamp together while inserting the connector. The connector is keyed so it will only go on one way. Replace the lamp access door on the optical engine. Replace the rear access cover. Air Filter Length of time between air filter replacements depends on the environment in which the WN-5230-S is operated. Check the air filter periodically and replace it when it is dirty, but don’t use it for more than 8,000 hours. An excessively dirty air filter can block air flow to the optical assembly and cause excessive heat buildup inside the WN5230-S. The air filter is most easily accessed from the rear of the WN5230-S by first removing the rear access cover. Air Filter Replacement, Front Access 70 September 1999 1. Turn off the power Switch off the WN-5230-S using the remote and allow the cooling cycle to complete (30 seconds) before switching off the AC power at the rear-panel switch. 2. Unplug power cord Remove the AC power cord from the display. 3. Follow appropriate steps for screen removal Follow the steps outlined for Lamp Replacement to remove the Standard Screen. If the screen is Ultra-Thin Mullion or Blackscreen, the air filter must be replaced from the rear. 4. Open the projector compartment hood There are two spring latches on the projector compartment hood. Pull these latches towards each other and pull the hood towards the front of the display to open it. 5. Replace the air filter The air filter is located behind the two cooling fans on the right. Use a flat blade screwdriver to pry the filter to the left. When the filter has cleared the bracket, carefully (to avoid dropping dust) remove it from the display. WN-5230-S VideoWall User’s Guide Air Filter Replacement, Rear Access 1. Turn off the power Switch off the WN-5230-S using the remote and allow the cooling cycle to complete (30 seconds) before switching off the AC power at the rear-panel switch. 2. Unplug power cord Remove the AC power cord from the display. 3. Remove the rear access cover Unfasten the 9 quarter-turn screws on the rear access cover and remove the cover. 4. Replace the air filter The air filter is on the left side of the display. To remove it, pull it to the right. Cleaning the Screen and Mirrors The best way to clean screens and mirrors is with clean, dry, compressed air and try to blow off the debris. If this does not work (a finger print, for instance) use a good quality optical cleaning solution and lint-free paper wipes or cheesecloth. Note: Apply the liquid cleaning agent to the tissue first; don’t spray it directly on the mirror or screen. This will sometimes appear to leave a light residue, but it will buff off, leaving a streak-free mirror. Because the mirrors are frontsurface mirrors, use care when cleaning them. Some representative cleaning products are: • Zero Charge Screen & Keyboard Cleaner, made by Tech Spray, Amarillo, Texas; (803) 372-8523 • Klear Screen Laptop & Computer Screen Cleaner, by Merridrew Enterprises, Danville, California; (510) 838-8774 • Sparkle, made by Paulson and Roles, Portland, Oregon; (503) 282-3289 The inside of the screen is harder to clean; usually the problem on the inside is finger prints. Do not use cleaning products on the inside of the screen. Instead, use a little isopropyl alcohol on a piece of cheese cloth, and don’t press hard. Don’t buff it off. Let the alcohol evaporate. CAUTION The screen is a laminate of two pieces. If excess liquid runs down the screen and collects at the bottom, it can wick up between the two parts. This is nearly impossible to correct. 71 Clarity Visual Systems Troubleshooting This section provides tips and strategies for resolving problems or issues you may encounter, either during installation or in normal use of the WN-5230-S. Many problems can be rectified without the need for service by following the troubleshooting steps below. If you are unable to resolve the problem by following the suggestions listed under the Failure Symptoms column, you will need to contact your service provider. Power and Start-Up Problems When AC power is applied to the unit by turning on the main AC power switch, the display enters a 30 second standby-delay period to prevent ignition of a hot lamp. During this time, the display will not accept commands from the remote control. The unit enters the Standby mode when the 30 second standby-delay sequence is complete. The display is ready to accept an “ON” command when the Standby LED comes on. This is the sequence of events that must occur for a WN-5230-S to power-up and display an image. 72 September 1999 WN-5230-S VideoWall User’s Guide Normal Power-Up Sequence 1. Attach acceptable AC power to the display 2. Turn on main power switch Sequence Note Failure Symptoms At This Part Of The Sequence The power module is auto ranging – no voltage selection is necessary The main power switch is located on the back of the WN-5230-S, next to the connector that the AC power cord plugs into The switch also acts as a circuit breaker in case of power overload The switch light indicates when AC power is applied and the switch is on 3. Electronics go into standby-delay mode Standby LED flashes for 30 seconds The status LEDs are located on the rear connector panel 4. Display is in a ready state waiting for an ON command Standby LED does not come on at all • Check the voltage at the wall outlet • Check circuit breaker switch on power supply • Contact your service provider STBY LED stays on solid LAMP and FAN LEDs are off If Auto On is enabled in the Misc Control menu, the display will attempt to turn on automatically after the 30 seconds have elapsed 5. When the display receives an ON command the fans turn on and the lamp ignites Buzzer will beep once Fan turns on FAN and LAMP LEDs light STBY LED goes off The time that it takes for the lamp to start after receipt of an ON command is about 2 seconds times the Monitor Unit ID setting on the rear connector panel. Normal Power-Up Sequence Sequence Note Electronics go back into standby-delay mode (the fans will run and the FAN LED will stay on while in this standby mode) • Verify that the interlock switches are fully closing - both are on the chassis there is one located behind the screen on the left side and one behind the right edge of the rear access cover • Contact your service provider The lamp doesn’t ignite • Verify that the lamp power connector is plugged in • Replace the lamp. • Contact your service provider Failure Symptoms At This Part Of The Sequence 73 Clarity Visual Systems 6. The electronics turn on the DLP engine and start sending data to it If there is video present on the selected source (see Source Select in menu), the video image will be displayed If there is no video present, the message “SOURCE ABSENT” will be displayed. Menus can be accessed and settings saved and changed Menu can be selected, but no video is present • Make sure that the correct source is selected in the menu • Verify that the Curtain option in the menu is not on • Check the video cable connections • Contact your service provider SOURCE ABSENT message is displayed • Select the correct source in the SOURCE SELECT menu • Verify that the video cables are plugged in • Verify that the source and cable are outputting a video signal using the same cable and source on another display • Contact your service provider No menu or video can be displayed • Replace the remote batteries and/or remote • Check the lamp • Contact your service provider 74 September 1999 WN-5230-S VideoWall User’s Guide Much of the preliminary diagnostics can be done by observing the 3 LEDs on the rear connector panel. Table 2 shows the LED combinations for the most likely failure modes if the WN-5230-S is not operating correctly. Standby LED Fan LED Lamp LED Indication Flashing slowly Off Off Normal operation after AC power is initially applied Flashing slowly On Off Normal operation or Interlocks open. See Note 1 on the next page Flashing fast On On An “on” command has just turned the display on and the optical engine is being initialized. This should not take more than 10 seconds. Off On On Normal operation or lamp problem. See Note 2 on the next page On Off Off Display is in Standby mode Table 2 Note 1 If the STBY LED is flashing and the Lamp LED is off, one of two conditions exist. Either the display was just shut down normally with the On/Off button or the unit has shut itself down and the likely cause is that the interlock circuit is open. The interlock circuit consists of switches behind the front screen and rear access panel. These prevent accidental exposure to hazardous voltages when the display is turned on. Verify that the screen and rear access cover are in place. If the problem persists, contact your service provider. Note 2 If the STBY LED is off, the Lamp LED is on, the Fan LED is on and the lamp is not lit, the electronics module is operating and the likely problem is with the lamp or it’s power system. If replacing the lamp and restarting the WN-5230-S does not resolve the problem, contact your service provider. 75 Clarity Visual Systems Image Problems Follow these steps in order.

Rear Panel Indicators Indicator STBY Description The green STBY light emitting diode (LED) is on steady when unit is in Standby mode and main electrical power is switched on. This LED blinks for 30 seconds when the main power is initially switched on or when the lamp is switched off to enter Standby mode. When it is blinking, the power on button for the lamp is inhibited. This LED will blink at a faster rate when the lamp is being ignited. 84 September 1999 FAN This is a green LED that is on when the cooling fan is running. It remains on for the 30 second cool-down cycle after the lamp is switched off. It is on during the initial 30-second period after AC power is applied. LAMP This is also a green LED. It is on when the display electronics has turned on the projection lamp. TEMP (Not functional in the WN-5230-S) REMOTE Indicates activity of the IR sensor. Stray Infrared radiation causes a faint glow and flicker. A signal from the Remote Control causes a 1/10th second flash. WN-5230-S VideoWall User’s Guide SOURCE On = valid source detected on the selected input. If this is off, either the wrong source is selected, or the source has no signal in it. GLOBAL This LED glows whenever data activity is detected at the RS-232 connector. It does not matter whether the packet was addressed to this unit on not, or even whether this is a command formatted for Clarity display use. It tells you there is a good connection to the controlling computer. The brightness of the LED is proportional to the density of the incoming data. LOCAL This LED glows very briefly whenever a valid packet of data is detected at the RS-232 connector and the packet is meant for this unit. It may be a global command, or a command addressed specifically to this unit. This display unit will try to execute this command. It will return an acknowledgement (ACK) only if the command was addressed to this unit exclusively. 85 Clarity Visual Systems Rear Panel Connectors Connector 86 September 1999 Description MAC Macintosh II data signal input, 800x600 or 640x480 pixels. 15-pin D-Sub, female.

WN-5230-S VideoWall User’s Guide Rear Panel Controls Control MONITOR ID Description 16-position rotary switches select a unique Monitor ID number for each unit in a video wall configuration. The two switches have a total number of 256 individual Monitor ID settings. GROUP - ID numbers are 0 – 9 and A – F for a total of 16 different settings. Each number is equal to that number times 16. A setting of 3 is equal to 48. UNIT - ID numbers are 0 – 9 and A – F for a total of 16 different settings. Each number is equal to that number times one. A setting of 3 equals 3, a setting of B equals 11. The Monitor ID number is the combination of the Group ID plus the Unit ID. A Group ID number of 2 and a Unit ID number of 5 equals a Monitor ID of 37. This setting also delays the time between an “on” command to the VideoWall and the ignition of the lamp. The delay is approximately 2 seconds times the Monitor Unit ID number. POWER Power On/STBY push-button switch. Controls power to the lamp and fans by toggling unit between ON and STBY modes. Power On/Off Rocker switch near the A/C power input connector. Main AC power switch. Remote-Control Use the remote control or RS-232 input for all setup and control functions. The remote must be pointed directly at the display for the VideoWall to “see” the remote’s commands. The most reliable position for remote control of the display is on an axis perpendicular to the front of the screen. The farther away that the remote control is from the display, the weaker the signal will be when it reaches the screen. The weaker the signal, the less reliable the control of the display will be. The remote is powered by two 1.5 volt AAA batteries. Remote Control Functions Some on-screen sub-menus can be accessed directly by pressing the specific menu item’s associated button on the remote control. 87 Clarity Visual Systems Remote Button 88 Description On Switches the display on when the Standby LED is on steady.

Commands should be paced using the ACK, NAK, UNK, or ERR responses from the display. Standard RS-232 levels, +/- 12V, are used. Some laptop PC’s use ground and +5V and are not always successful in communicating with the display. The display’s RS-232 port is always active except during the boot process which is the first 10 seconds after power is applied to the display electronics. In single address mode (not when global commands are being used) the host machine should wait for an ACK, NAK, UNK or ERR response from the display before sending the next command to avoid overrunning the input buffer. When global commands are sent, the displays will not return a response, so a delay of ½ second should be maintained between commands to avoid possible errors. The protocol for communication to the display consists of a 7 byte command line as described below. STX(1 byte) IDT(2 byte) CMD(3 byte) ETX(1 byte) Where; ASCII STX - Start of transmission character, = 02h 98 Description Abbreviation Hex Decimal Start of Text STX 02 2 September 1999 Character Control Ctrl- B WN-5230-S VideoWall User’s Guide IDT – IDT is a 2-byte ID character string. Monitor ID bytes are used to identify which display will receive the RS-232 command. This is a 2 byte address that is set by the Group and Unit Monitor ID knobs on the display’s connector panel. Each knob has 16 possible settings with the Group setting the high byte and the Unit setting the low byte. The address consists of the ASCII Alphanumeric characters (0-9, A-F for the Group setting and 0-9, A-F for the Unit setting) providing the means to control up to 256 combinations (00 to FF). Multiple units can be controlled simultaneously by using the ASCII character for the asterisk (*) in place of either or both of the IDT monitor ID bytes. The (*) is a wild card character and provides a means to control multiple units simultaneously. There are four types of addressing that are supported. 1. Single address mode – the entire address is specified: 00, 01, 02, A2, AA, FF are valid examples. Only the single display that matches this address attempts to execute this command. An acknowledgement is sent in this mode. Note: Do not set several displays to the same Unit and Group address. If two displays have the same Group and Unit ID, and a Single Address Mode command is sent to that address, both units will send an acknowledgement at the same time, causing some confusion in the data on the RS-232 line. 2. Group address mode – the group part of the address is specified, while the unit part of the address is not: 1*, 9*, A*, F* are valid examples. All displays that match the group number attempt to execute this command. No acknowledgement is sent in this mode. 3. Unit address mode – the unit part of the address is specified, while the group part of the address is set as global: *2, *9, *F are valid examples. All displays that match the unit number attempt to execute this command. No acknowledgement is sent in this mode. 4. Broadcast mode – both group and unit are “*”, so the IDT part of the packet is “**”. All displays attempt to execute this command. No acknowledgement is sent in this mode. All addressing is done in hex. CMD - CMD is a 3-byte command character string. These command strings are shown in the table listing the RS-232 command codes. ASCII ETX - End of transmission character, = 03h Description Abbreviation Hex Decimal Character Control End of Text ETX 03 3 ❤ Ctrl- C For example, to turn on a display with an address of 06, it would need to receive the following command: 99 Clarity Visual Systems ☺ 06 PON ❤ Note: For a data packet to be valid, it must start with STX and end with ETX, and the time from STX to ETX must be less than one second. 100 September 1999 WN-5230-S VideoWall User’s Guide RS-232 Control Items Notes: * Indicates an ASCII character is returned from the cube in this location. $ Indicates 8-bit data is returned from the cube in this location # Indicates 8-bit data is transmitted to the cube in this location 1 ACK or NCK will be transmitted following the video cube receiving a non-global instruction.
